Here's one you don't see every day. Delta Airlines passed out napkins for people to flirt with strangers on a plane. It says, "Because you're on a plane full of interesting people and hey...you never know," and then on the back is a place for your name and cell phone number so you can, well, start dating. One napkin says, "Write down your number and give it to your plane crush." Not everyone thought it was a good idea and called it "creepy" and social media had a field day. Coke and Delta both apologized for the napkins, but chances are good they knew what they were doing all along. But the napkins are gone.
